Replacement parts

Name	Part no.	Stock	Unit
Feed tire	035-14303 021-14301	2 / riso	Paper feed
	The two matching rollers in the 1st paper feed—the outer one is the "scraper" (feeds multiple sheets in) and the inner one is the "pickup" (separates the top sheet). Each is an inner plastic core and outer tire (this is the part for the tire). The inner (pickup) roller should use OEM, the outer (scraper) roller can use generic—generic tires tend to be eccentric (egg-shaped) and a smaller diameter than the originals. The RP uses 3 rollers, two of which are tires on a proprietary core, but the third roller requires a solid feed tire.
Stripper pad	019-11833	3 / riso	Paper feed
	The stripper pad puts upward force and friction on the multiple pages that are fed into the pickup roller, so that the teeth of the tire only propel the top sheet into the riso. It is the rubber part that wears the fastest and must be replaced regularly for stable paper feed. Very old risos may use a different stripper unit, which takes an older stripper pad type (a thin square), otherwise this part is universal. An alternative grey stripper pad is listed under part no. 019-11834—it uses a harder material, which is meant to last longer and be better for heavier paper stocks.
Feed roller core	023-12306 021-14302	1 / riso	Paper feed
	The plastic core of the feed rollers (the feed tires are stretched around these) contains a one-way bearing, which allows the paper to be pulled freely through the 1st paper feed by the 2nd paper feed and press sections. This bearing wears down over time, which will either decrease the feed power or cause the roller to drag on the rest of the system. Replacement cores ship dry, and will need oiling.
Exit belts (RP)	629-94570 629-93280	1 set	Paper ejection
	Exit belts transport paper out of the riso—a suction fan pulls air down through holes in the belts to hold the paper to them while the main motor powers the belts. The RP uses 4 belts, 2 wide ones with holes, and 2 narrower solid ones—a full set is 2 of each. As they wear, they will stretch out and slip on their rollers—paper will become stuck in the exit area (particularly larger sheets of heavier stocks). Belts can be tested by dragging them with a fingertip—each pair of belts should move together—if individual belts slip, it's a sign that all should be replaced.
Separator collar (RP)	030-15113	1 / riso	Paper ejection
	A small, wide roller that sits on a bracket at the back of the bar supporting the separator needle. When it breaks down, the separator needle will catch more frequently on the drum, resulting in stock drums and lost timing. This part is past the point of replacement on all RP machines—if it has not yet been replaced in the life of the machine, it should be. This is the most common cause of drums stuck in these machines, which can also result in permanent damage to the back flange of the drums.
